I thought I'd share the new version which is quite an overhaul of the old one. It has colors, can zoom in/out, move around, and the ifs codes aren't hard coded.
The controls are very clumsy though. Would've been a lot better if I made a console or something like that.
But this was just a test application from the beginning anyway.
